Assessment of toxicity of two nitroaromatic compounds in the freshwater fish

Hongyan SHEN, Jixi GAO, Jinsheng WANG

Frontiers of Environmental Science & Engineering 2012, Volume 6, Issue 4,   Pages 518-523 doi: 10.1007/s11783-012-0427-6

Abstract: This study was conducted to evaluate the toxicological response of -nitrotoluene and -nitroaniline to the key fish species, . A freshwater fish bioassay based on the 96 h was used to estimate the single and joint toxicity of the two chemicals. The toxicity of -nitrotoluene was greater than that of -nitroaniline based on 96 h values of 40.74 mg·L and 48.99 mg·L , respectively. Both compounds had moderate toxicity toward , and this toxicity increased with the exposure duration and concentration. Binary mixtures of the compounds were more toxic than the individual compounds at 96 h, and they acted upon partial addition. When the exposure time was longer, the toxicity increased for mixtures of compounds with the same concentration or toxicity. The results of this study suggest that exposure to a combination of these chemicals would result in a higher environmental risk in aquatic systems than exposure to either compound alone. Further research is needed to investigate the combined effects and sublethal toxicity of -nitrotoluene and -nitroaniline, since they are both still used in China.

P50 auditory sensory gating in first onset schizophrenics and normal healthy adults

WANG Hongxing, ZHANG Mingdao, CHEN Xingshi, LOU Feiying, LIANG Jianhua, CHEN Chong, SHI Tiantao, LU Qiulin

Frontiers of Medicine 2007, Volume 1, Issue 4,   Pages 429-432 doi: 10.1007/s11684-007-0084-5

Abstract: The aim of this research was to investigate the variations of P50 auditory sensory gating (P50) in normalBy using the American Nicolet Bravo electromyography/evoked potential (EMG/EP) system, P50 was measuredCz, Fz and Pz respectively), there were no statistical differences (>0.05) between S1 and S2 evoked P50peak latencies (S1-P50 and S2-P50); the amplitudes of S2-P50 [(2.2±1.4), (2.3±1.5) and (2.1±1.4) μVThe first onset schizophrenics had sensory gating deficits, which could be quantified by P50.
